Debt Book now speaks your language. NEW • Arabic — the whole app, translated and laid out right-to-left. Buttons, back arrows and list chevrons all sit and point where they should. • Spanish — the whole app, translated. • Choose your language when you first open the app, instead of the app guessing from your phone's region. You can change it any time in Settings. IMPROVED • Currency names and date formats are now translated too, rather than staying in English inside a translated screen. • Bengali covers every screen again, including the newer ones — receipts, the side menu and the rebuilt profile page. FIXED • Typing an amount in Arabic showed nothing until you tapped Done. The digits now appear as you type, right next to the currency symbol. • The cursor sat in the middle of the "0.00" placeholder instead of at the start of it. • Back buttons and row arrows pointed the wrong way in Arabic. • Choosing "Clear All Data" reset the app to English. Your language now survives it — clearing your records is not a request to change language. • Corrected a mistranslated heading in Bengali Settings.
